Ulster beat Edinburgh 14-7 last night but they suffered a number of injury blows on the night.
Iain Henderson, Darren Cave, Peter Nelson,Dan Tuohy and Franco van der Merwe wall suffered injuries at Kingspan Stadium.
The most worrying of all the blows was that to Irish international Iain Henderson
With just four minutes on the clock, Henderson pulled up trying to chase down a Nick Williams block-down and, after a break in play for treatment, was stretchered off.
Ulster face Toulouse in back-to-back Champions Cup games next and the Ireland international may well miss out on the fixtures.
Post-match, Kiss told BBC that it was too early to tell the extent of the injuries to his quartet. Henderson will go for a scan within the next 24 hours to learn the extent of his injury.
Any serious ligament damage could see the 23-year-old in danger of missing the start of Ireland’s Six Nations.
